Magnetic Properties of La0.7Sr0.3Mn1-xNixO3 Perovskites
Abstract
Using a SQUID magnetometer, we have studied the magnetic properties of La0.7Sr0.3Mn1-xNixO3 (x=0.05, 0.10, 0.20 and 0.30) perovskites. Both temperature dependent and field dependent magnetic measurements show that the Curie temperature decreases as a function of doping, ranging from 380K in La0.7Sr0.3MnO3 to 300K in La0.7Sr0.3Mn0.7Ni0.3O3. Both magnetic measurements and neutron-diffraction refinements indicate long-range magnetic ordering in samples at low temperature. Transition phases from paramagnetic to ferromagnetic to antiferromagnetic ordering in samples at room temperature.
